LOCK.

provements in Locks, of which the following is a specification;

This device is intended as a lock such as is sometimes termed a safetybrace or bar lock,.wherein a bar is hingedly securedto a permanent fixture and is slidablyenga ged with a door or gate.

' In the development of my-invention I have devised numerous ways for accomplish ing the desirable result, as Ihave found that difl'erent styles ofdoors require a different arrangement of the locking bar. The'bar' as arranged to operate on a sliding door belng found impractical on a swinging door, and

I have found that the lock necessary .to secure a simple sliding door need not be so complicated as one required by a duplex 'door or gate.

CID

All of these arrangements, their construction and method of operation will be fully set forth as the specification progresses and it will be observed that the lock herein set forth may be used not only upon sliding elevator doors but also upon swinging doors or hinged covers or in any place where a strong lock is desired.

The following is what I consider the best means of carrying'out this invention.

The accompanying drawings form part of thisspecification, in which Figure 1 shows in elevation the lock used ona double slide or elevator door. Fig. 2 shows in'plan the device used on a swinging door. Fig. 3 shows in elevation a part removed. Fig. 4 shows in end elevation the part shown in Fig. 3. Fig. 5 shows a modification ofthe structure set forth in Fig. 2-. In this modification two sliding bars are used. Fig.6

shows the door in an open position. 7

Similar reference numerals indicate like parts in all the figures where they appear.

As the devices shown in the separate figures are alternate constructions differing from each other in many essential details, Iwill describe each separately. 7

Referring to Fig. 1, at1,,I have shown the locking bar, a straight flat bar of steel perforated at each end. A bracket 2 adapted to be screwed securely to a wall or other permanent support is provided with a ring 3, which passes through the perforations in one end of the rod land produces therewith Specification of Letters Patent.

a flexible joint adapted to be hinged vertically or slid horizontally. Arranged adja: cent to the other end of the bar 1, I provide a rod 4 of any desirable length and whichI have secured by means of sockets5 and 6 and brackets 5 and 6 at a point quite close.

to the inner edge of a sliding'door A. Slidable upon the rod 4 is a member provided with a grip '8, which is a cylinder through which the rod 4 is free to pass and formed integral with this cylinder are the outwardly extending lugs 9 and 10 each provided with a screw as shown at 11 and 12. These lugs 9 andlO are formed of two parts of equal shape and size separated from each other a sufiicient distance to allow the bar 1 tobe inserted and there to be loosely held by means of either of the screws 11 or 12'. I

provide two of the lugs as shown at 9 and 10,

but operation I use but one, theother lug serv ng only if it is desirable to extend the bar 1 in the opposite direction, for operating a door having two or more sliding members. In operating thislocking bar the handis placed about the grip 8 and the grip is lifted or slid longitudinally upon the rod 4. The door may then be opened by causing it to slide toward the bracket 2. This will cause the-end of the rod 1 and the grip 8 and parts secured thereto to travelupward on the rod 4 until the door is fully opened, andit is my intention that the parts shall be so arranged and conditioned that the rod 1, and grip 8 will only obtain such a position as will cause them to. constantly tend.toaclose the door..

If. it is found desirable to securethe door open or closed a pin may be placed in one of the perforations 13, a series of which are shown in the rod 4.

If the' door be of the construction as shown'in Fig. 1 wherein the parts A and B slide back over the part C, it becomes necessary to place an operating bar to move the part B. I do this by connecting to the lug 10 a rod 1 pivotally connected to the part B at 3 Nowlifting the grip 8 will cause the rod 1 and 1 to be drawn inward and as the parts A and B are movable they will both slide back over the part C, the inner edge of the part B passing under the angle members 5 and 6*. And now referring to Fig. 2, a modified form, I have shown the rod placed in a horizontal position. This rod 20 is secured by means of the brackets 21 and 22 and slidable thereon I have arranged a a the member 23'slides upon the rod 20.

" grip 23 though in this instance having the lugv24 arranged upon its front face. A locking bar 25 operable inthis lug 24: and: hingedly secured therein byimeans of a Sscrew may also be a fiat steel rod; but 0011:" side'rably shorter than the rod 1' shown in Fig.7 1. A bracket 27 firmly secured to: the

Wall or other permanent support. receives the inner end of the bar 25, and hingedly retains it by means of the screw '28. A pin 29, which may be inserted into any one of a se ries of holes in, the bar'20 locks the sliding:

member 2-3 in a predetermined position;

The door to which the bar 20 is secured hinges at 30', and whenthis door is opening AtiFig. 5, 1 have shown a modification of the structure shown in Fig. 2. "I have found that some swinging doors are too narrow to 20 accommodate a horizontal rod 1 sufliciently long to allow the door to openfully. I have therefore placed a second slider rod4c5, upon the permanent abutment; in lieuof the bracket 27. In this construction the members 46 and 47 will both slide allowingthedoor to open to its full extent, and as both the slider rods may be perforated it will re r quire two pins 29 to secure' the slides fLGQa-nd lfiinposition. a

It is obvious that these devices may-b operated in conjunctionwith a 'key by merely placing a key operated abutmentadj acentto the sliding members in Figs; 1 and 2, and'by arranging akey to lift the inner V, projecting end of thebar 3 3 in Figs, 3 and 4. v Other modifications may be made withinv V the scope offthe appended claims'without departing from the principle 'orisacrificing the advantages of this invention.
